Important Note: For a visual step-by-step guide, it is highly recommended to search for "kuflant disassembly" on YouTube. The manufacturer provides detailed video tutorials that complement these written instructions.
Required Tools (Included)
- Custom-made Spudger
- Triangle Pick Openers (2)
- Tin Wire (Solder Wire)
These custom tools are designed to help safely remove the toothbrush bottom cover and prevent damage to internal components, such as the charging coil or base cover, which can occur with improper prying methods.

Also shown are the custom disassembly tools (spudger and triangle picks) designed to prevent damage during opening, such as to the charging coil or base cover.
Battery Features and Soldering Tips
The replacement battery features a V-shaped design that limits the distance between contacts and the board, preventing short circuits. The solder contacts are upgraded for enhanced durability.

When soldering the new battery, ensure the following:
- Recommended Soldering Temperature: 350°C (662°F).
- It typically takes 2-5 seconds for the solder to melt with a soldering iron.
- Ensure the solder points on the PCB are perfectly cleaned before attaching the new battery.
- Position the battery with the "+" (positive) and "-" (negative) poles in the correct orientation.
- Verify that the battery pins are properly inserted into their respective slots on the circuit board.

Maintenance
The shaft rubber seal plays a crucial role in preventing water from seeping into the toothbrush handle and damaging internal components. It is recommended to replace the rubber seal every 3 months to maintain the integrity of your toothbrush and prevent future issues.
Troubleshooting
If your toothbrush is not responding or not charging at all, even after replacing the battery, it indicates that the PCB (Printed Circuit Board) or motor of the toothbrush is likely damaged. In such cases, replacing the battery will not resolve the issue. This type of damage is often a result of water ingress due to a deteriorated rubber seal.
